Answers
Let a number of notes are 2x, 3x and 5x.
According to question, 100 x 2x + 50 x 3x + 10 x 5x =4,00,000
\Rightarrow\ 200x+150x+50x=4,00,000⇒ 200x+150x+50x=4,00,000
\Rightarrow\ 400x=4,00,000⇒ 400x=4,00,000
\Rightarrow\ \frac{400x}{400}=\frac{400000}{400}⇒
400
400x
=
400
400000
[Dividing both sides by 400]
x = 1000
Hence, number of denominations of ` 100 notes = 2 x 1000 = 2000
Number of denominations of ` 50 notes = 3 x 1000 = 3000
Number of denominations of ` 10 notes = 5 x 1000 = 5000
Therefore, required denominations of notes of 100, 50 and ` 10 are 2000, 3000 and 5000 respectively

Answer:
Step-by-step explanation:
2x*100+3x*50+5x*10 = 400000
200x+150x+50x=400000
400x=400000
x=1000
so number of notes of 100 rupees = 2x=2000
number of notes of 50 rupees = 3x=3000
number of notes of 10 rupees = 5x=5000
